Extra Notes:
Vallance Naradoon East
Confirmed Map but no yield
Vallance Naradoon West
Confirmed Map but no yield
Keating Middle Fays Updated rates but there is a Nill and skinny 0? Need to contact to Ash to proceeded I think we have yld data .
problem with extracted yield data Christina will fix soon?

Ideally the yield would be the same in both strips (GSP and Alt GSP), and / or the yield would not be significantly different.
Significant yield differences between the two strips suggest that there is a high degree of variability between the two strip that were applied with the same fertiliser.
This may occur because the strips have underlying soil, plant growth conditions.

Different comparisons are made between high, medium and low fertiliser rates for each zone.
Comparison of yield response in the strip / zone per paddock between:
High fertiliser rate vs low fertiliser rate (yield for high fert rate - yield for low fert rate)
High fertiliser rate vs medium fertiliser rate (yield for high fert rate - yield for medium fert rate)
Medium fertiliser rate vs low fertiliser rate (yield for medium fert rate - yield for low fert rate)
The yield response is classed as ‘positive’ when higher rates of fertiliser results in higher yields.
The yield response is classed as ‘no response’ when higher rates of fertiliser results in no change in yields (this is defined as 0 +/- standard error)
The yield response is classed as ‘negative’ when higher rates of fertiliser results in lower yields.
T- test was also run for each comparison and the significant differences at p < 0.05 reported. Note that some significant values are not reported for the zone, this may occur when there is not enough data points to run the t - test (although there is still have yield values to make a comparison).
The below table shows what fertiliser rates were assigned to low medium and high fertiliser rates.

Different comparisons are made between the growers standard practice and fertilisers strips for each zone.
Comparison of yield response in the strip / zone per paddock between:
The yield response is classed as ‘positive’ when higher rates of fertiliser results in higher yields

The yield response is classed as ‘negative’ when higher rates of fertiliser results in lower yields.

The soil test results results in a recommended N and P rate.
Sean has done these calculations.
The recommended fertiliser rate was not always implemented, so I have worked out the closest match.
The approx recommended rate:
A = recommend rate - abs(rate 1)
B = recommend rate - abs(rate 2)
C = rate - abs(rate 3)
Then work out which has the smallest value A, B or C, this will be the approx recommended rate.
Then I assigned a rate lower and a rate higher than recommend rate for the comparison.
Higher and lower rates won’t always exist, for some paddocks.
In some cases the rates will all be higher or all be lower, while for other paddocks there will be choice to be made (which rates should be used).
If we need to choose what rates to induced it is best to use this rough rule:
Comparison of yield response in the strip / zone per paddock between:
Approx recommend rate vs lower fertiliser rate
(yield for app rec fertiliser rate - yield for lower fertiliser rate)
Approx recommend rate fertiliser rate vs higher fertiliser rate
(yield for app rec fertiliser rate - yield for higher fertiliser rate)
The yield response is classed as ‘positive’ when higher rates of fertiliser results in higher yields
The yield response is classed as ‘no response’ when higher rates of fertiliser results in no change in yields (this is defined as 0 +/- standard error)
The yield response is classed as ‘negative’ when higher rates of fertiliser results in lower yields.
T- test was also run for each comparison and the significant differences at p < 0.05 reported. Note that some significant values are not reported for the zone, this may occur when there is not enough data points to run the t - test (although there is still have yield values to make a comparison).

Review that the results look sensible and nothing needs re running - are the reports OK to send off?
The fertiliser applied has translated correctly to units of N or P.
Are the rates included in the comparison analysis sensible and what you want.
Are the paddocks to be included in the economics analysis?
